General description

The ABRASION INDEX TESTER is a process and laboratory machine, which is designed to determine the abrasion index of a mineral sample to be determined in accordance with F.C. Bond´s abrasion test method. The abrasion index tester utilizes an electrically driven drum and rotating abrasion paddle. The mineral sample is lifted by a mesh drum liner and dropped on to the steel paddle, which rotates in the same direction. The paddle is made to exacting standards of material and size and two square inches of this is exposed to wear. After running the test, the weight loss of the paddle is noted in grams, this represents the Abrasion Index (Ai) of the material.

Note: For comprehensive details of the abrasion index test it is recommended that the is user understands F. C. Bonds paper “Crushing and Grinding Calculations – Part II”

Technical features

3.1 Construction
The housing of ABRASION INDEX TESTER is made of steel plate varnished with high resistant painting.
Protective equipment
The milling chamber of the ABRASION INDEX TESTER is enclosed by a strong covering door. Starting of the machine is possible only with the door closed.

3.2 Technical details

Installation

4.1 Unpacking
Before the installation, carefully examine the delivery for possible damage or missing parts. Open the box and take the machine out of the box. Check that the machine has not been visibly damaged during the transport. Please keep the packing material for the duration of the guarantee period. In case of a complaint and return of the machine in unsuitable packing material, your guarantee claim will be lost. Check that the mains cord is compatible with the local standard. If any kind of damage occurred during transport, immediately make a complaint to the carrier. Any incorrect delivery or missing parts should be reported to the distributor.
After unpacking the machine open the front door to get acces to the black key for all small cover locks.
Use this key to access the back plate of the machine. Here there is a box situated with the paddles and the bottles needed for processing.

4.3 Connecting the power cord
The correct voltage and frequency for the ABRASION INDEX TESTER are given on the name plate. Ensure that these values correspond to the available power supply system.
Connect the power cord to a grounded wall socket. To avoid interference from noise, surges and spikes, a dedicated line is preferred. If no such line is available, avoid lines to which powerful electric motors, refrigerators and similar devices are connected.
The power can be turned on and off by the Emergency POWER switch, located on the left side of the housing of the machine.

4.2 Selecting the right place
When selecting the right place for the machine, please consider the following:

• Put the device on smooth, straight and stable table or frame.
• Make sure the bottom plate is situated at the edge of the table so that the hole in the product drawer can be pulled outside of the table platform.
• Leave enough space beyond the device.
• Leave enough space around the device, that you will easy control and maintain it.
• Don’t use the device in surroundings, where there are fast temperature and humidity changes. Also avoid places exposed to direct sunlight and places nearby heating devices.

4.4 Enviroment conditions
The machine has been built for operating in process and laboratory environment. Therefore the environmental conditions should be the following:

• Temperature from C to C
• Humidity up to 85% RH, non-condensing
• POWER switch (on the right side of ABRASION INDEX TESTER – switches ONor OFF the power of the machine.
• Green button – Start button
• Timer Display

Starting of the machine is possible only with the hood closed. Always start and stop the machine with START and Emergency key.

Instructions for use

5.1 General control panel

5.2 Removing the front plate
Open the front covering hood of the Abrasion Index Tester using the handle located at the covering hood (See Picture 1&2). Remove the front plate of the abrasion chamber by unscrewing the socket head cap screws as shown on Picture 3 and 4.

5.3 Inserting the mesh lifter
Ensure that a new test paddle is fitted to the rotor and securely clamped. Ensure that exactly 2” of this paddle protrudes from the rotor. Note that although the rotor has two sockets for paddle plates only one is to be fitted. Ensure that the capscrew on the empty socket is securely fixed to keep dirt out of the threads the charge as shown close the lid and secure it firmly.

5.4 Display troubleshoot
